Jiang Cheng decides to accompany (protect) the juniors on a night hunt; spoiler, it ends with a victorious battle, but at the cost of the fearsome Sandu Shengshou losing all dignity by being thrown into a muddy lake.
After numerous pleas from the four juniors (Lan Shizui was pale with guilt), he reluctantly decided to go to Gusu Lan so he could bathe, change his clothes and stay there for the night.
After obtaining Lan Qiren's permission ["Master Wei is absolutely right, Grandmaster Lan has a weakness for Sandu" Ouyang Zizhen muttered to the group], he decided to go after his next objective: new clothes.
Never before had Lan Jingyi been so quick to offer his own clean robes to Jiang-zhongzhu, but since the brat had grown enough in a period of 2 years to match his height, Jiang Cheng decided to accept them with a murmur of thanks.
Lan Jingyi had to sleep with one eye open in case Jin Ling decided to kill him, but he didn't regret anything.
Jiang Cheng returned to the juniors an hour later, showered and satisfied, wearing a lan robe that was far too light for his liking, his hair half-tied up to dry (Lan Jingyi's ears and Lan Shizui's neck turned a deep red). It only took a puppy face from a-Ling for Jiang Cheng to decide to prepare dinner for the four young men.
A domestic scene was seen in one of the lan kitchens: Lan Shizui and Ouyang Zhizen were cutting the vegetables while Lan Jingyi and Jin Ling followed any order that Jiang Cheng commanded.
All that calm came to an end when he heard the shrill laughter of a fox in the hallways, the distinctive "hmph" and a voice so soft it could be mistaken for the whistling of the wind. Jiang Cheng closed his eyes, counted to ten and mentally prepared himself for whatever might happen.
He definitely wasn't prepared for Lan Wangji and Lan Xichen to call him "mom" at the same time.
From that day on, whenever he became moody, Wei Wuxian would put an arm around his shoulders, play with the purple ribbon in his hair and publicly justify it by saying that his shidi's maternal instinct was out of control.
Wei Wuxian ended up being thrown into one of the lakes of Yunmeng Jiang (he has no regrets and would do it again).
